The accent and somewhat different. If a Portuguese citizen speaks quickly, a Brazilian may not understand and vice versa.

Brazillians can speak as fast as they want and we will understand them(at least I do). We watch brazillians soap operas since we are born, cara. lolI have a lot of brazillian friends(from my other interests, not from the bitcoin world) and when I speak with them I speak with brazillian accent. <--- That worried me for a while because I was afraid they thought I was making fun of them. I just can't help it, happens naturally Even when IM'ing them I use brazillian slang.
